'This invention relates to devices for marking powderlines, andparticularly for marking lines on siding boards, for guiding a saw.

In the operation of erecting frame buildings it is customary to provideperpendicular strips or molding on the corners of the buildings and thento cut the siding boards to fit between such mouldings and ordinarycasings on windows or doors. Difficulty has been found in marking lineson such siding for guiding a saw as the uncut boards are held outward bythe mouldings. Devices have been proposed for marking such lines byabrasions or scratches, but in many cases the material to be marked maybe warped or too hard to receive and show suitable lines. Again allknown devicesrequire the use of both hands for operation, and as onehand is usually required for holding the board in position to be markedfurther difiiculties are met.

It is therefore among the objects of this invention-to provide a devicefor marking such lines by chalk or other suitable powders as may readilybe made on any kind of material and uneven surfaces.

Another object is to provide a device that may be held and operated byone hand while the material to be marked may be held by the other hand.A'particular'object is to provide a frame for fitting across a boardwith a slot in the bottom thereof for discharging a marking powder tomake a line across any surface or board with an element for carryingsuch powder and means for raising the element and snapping the same downover the slot, throughwhich the line of powder is discharged upon thesurface to be marked.

With these and other objects to be hereinafter shownI' haveillustratively exemplified my invention by the accompanying drawings, ofwhich: Figure 1 is a perspective view of the device mounted over a boardin position to be marked. Figure 2 is aside elevation view in sectiontaken on line 22 of Figure 3showing a spring and levers in normalposition. Figure 3 is a top plan taken on line 33 of Figure 2. Figure 4is a fragmentary section view showing the spring and levers in loweredposition. Figure 5 is a crosssection view taken on lines 5-5 of Figure3. Figure 6 is an enlarged perspective fragmentary view with partsremoved. Like numerals on the different figures represent like parts.

Numeral I represents a hollow frame preferably formed of wood or plasticand opened along the bottom. This opening is normally closed by faceplate 8 which carries upturned edges 9 for clamping upon the frame fornormally holding the plate thereon. The plate is provided with arelatively narrow slot l0 along the face thereof excepting short ribs Hfor rigidity. From each end of the frame and at one side of the slotarms l2 are extended below the plate for reaching over'the oppositeedges of the boards to be marked, and on the lower ends of the arms arenarrow flanges l3 extended sidewise to position in alignment below theslotfor' resting against the molding to determine the position of theline to be marked. The arms also carry fingers l4 extending inwardtowards each other for reaching up along the under side of the board totouch the moulding when the lower edge of the board and lower end of themolding are even or' when the lower edge of a board is below the bottomof the moulding.

Above the plate and normally resting upon the same is a trough orcontainer element V ii for carrying a supply of marking powder. Thetrough is loosely positioned within the frame and is preferably providedwith a number'of partitions I! to prevent the chalk or other powder Hifrom falling to the lower end when held perpendicularly. The bottom ofthe container or trough is provided with a longitudinal slot l8 which isnormally located above the slot in the plate on the frame but separatedtherefrom by a screen l9 with meshes of suitable dimensions for normallypreventing the escape of the powder; but suitable to permit the powderto sift through when jarred. A cover or cap 20 is normally attached toand over the container by means of screws 2| meshing in holes 22 in thepartitions. In some instances it may be preferred to use containers forthe chalk to be formed of felt or other suitable porous material inwhich the chalk may be impregnated or carried, and which may be attachedto, the cover in lieu of the trough container or other element.

For normally maintaining the chalk container or carrier against thebottom plate, a coil spring 23 is mounted centrally on the cover withthe top of the spring extended up and sustained against a thrust washer24 which is affixed on the lower portion of a bolt 25, which latter isslidably mounted through a bushing 26 in the top of the frame. The lowerend of the bolt is projected down between the upper coils of a spring tosteady the same when extended. A knob 21 on the top of the bolt orplunger, facilitates the manual operation thereof. The knob may beconnecte with the bolt as by screw 28.

In order to cause the container to rise against the spring 23 when thebolt is being depressed, levers 29 and 30 are mounted over suitablefulcrums 3| and 32 which are supported on side posts 33 and 34 in slots35 of the frame. The inner ends 36 of the levers normally rest slightlyunder the edges of the washer, and the outer against the inner margin ofthe moulding as B,, illustrated in Figure 1, so that the slot in theface plate will lie parallel or in alignment with the margin. The boltis then depressed, which compresses the spring 23 and the washerdepresses the inner ends 36 of the levers and thereby the outer ends ofthe levers 31 are elevated and the container raised against the spring23 by .the slats 38 which latter are attached to the cover by anysuitable means. As soon as the washer hasdepressed the innerends of thelevers to the positions shown in Figure 4 the levers thereupon arereleased and the spring 23 eX- panding, forces -or snaps the containerdown upon the. face plate which forces a line of chalk or marking powderacross the board or surface to be marked. The bolt is then released andthe spring 23 forces the washer up against the slopand back to theirnormal position by the resiliency ofthe slats, The levers are providedwith shoulders or angles 40 which prevent them from extending inward tointerfere with the spring 23, but do not interfere with rising'of theinnerends and backing t permit the escape of the Washer above the same.While I have described my invention by references tocertain forms ofconstruction, I do not limit my invention thereby, but retain the fullscope of my invention, and within the scope of following claims,-asbroadly construed.

Having described my invention I claim as new: 1. A device for markinglinesacross boards comprising a hollow frame, a plate on base thereofhaving a longitudinal slot therein, a container divided intocompartments to carry marking powders adjustably positioned over thebase and having a longitudinal slot in the bottom thereof, a spring lfornormally pressing the container toward the plate, fulcrums on each sideof the spring, levers mounted over the fulcrums having their inner endsadjacent the spring and their outer ends connected to the container byflexible slats, a thrust washer movably mounted above thesprling andhaving its outer edges extended over the inner ends of the levers, meansfor depressing the spring and the inner ends of the levers until thecontainer is elevated and the washer released from the levers to permitthe container to snap down against the plate for distributing a line ofchalk through the slots.

2. A siding marker including a rectangular casing, a bearing face plateon the bottom of the casing having a slot longitudinally along the same,a container slidably mounted above the plate andhaving a plurality ofcompartments for carrying marking powders and having a correspondingslot along the bottom thereof, a spring for maintaining the containeragainst the base in normal position, fulcrums extended above the frame,levers mounted over the fulcrums for raising'the casing, resilient slatsattached at their lower ends .to the casing and their upper endsattachedlto the outer ends of the levers for actuating the levers andraising the casing when the sprmg is compressed, a bolt-s-lidablygdisposed above the spring for manually compressing-thespring, a thrust washer attached to lower end of the bolt for depressingthe inner ends of. the levers for-raising the casing against- -thetension of the spring and ;a knob -.on-the belt for actuating the samewhereby the casing is first-raised and then" forced down by theoperator.

3. A device for -marking powder :lines across boards and surfacesincluding a case having a slot along the lower face thereofla containerfor powdermovably mounted in the case, a spring for normally pressingthe container toward the face, fulcrums across vthe case,-levers mountedoverthe fulcrums each with one end thereof connected'to the containerandthe other endrthereof extended toward the spring, downturned lipson'the inner ends-of the levers adjacent to the spring, a thrust washeroperable above :the spring and inner ends of the levers adapted tocompress the spring until thewasher has passed-beneath the lips wherebythe container is lifted and snapped back upon the base and the washerraised above the lips and levers.

4.
